Invalid bound statement (not found): com.heima.mapper.MyMapper.selectList

As an AI language model, I cannot determine the specific issue without seeing the code and the context. However, the error message suggests that the bound statement "com.heima.mapper.MyMapper.selectList" could not be found. This could be due to a typo in the statement or the file path, or the statement might not exist in the MyMapper class. You should check the code to ensure that the statement is properly defined and spelled correctly.
